+    .SYNOPSIS
+        Adds an image to a worksheet in an Excel package.
+    .DESCRIPTION
+        Adds an image to a worksheet in an Excel package using the
+        `WorkSheet.Drawings.AddPicture(name, image)` method, and places the
+        image at the location specified by the Row and Column parameters.
+        
+        Additional position adjustment can be made by providing RowOffset and
+        ColumnOffset values in pixels.
+    .EXAMPLE
+        $image = [System.Drawing.Image]::FromFile($octocat)
+        $xlpkg = $data | Export-Excel -Path $path -PassThru
+        $xlpkg.Sheet1 | Add-ExcelImage -Image $image -Row 4 -Column 6 -ResizeCell
+        
+        Where $octocat is a path to an image file, and $data is a collection of
+        data to be exported, and $path is the output path for the Excel document,
+        Add-Excel places the image at row 4 and column 6, resizing the column
+        and row as needed to fit the image.

+# Add-ExcelImage Example
+
+Adding pictures to an Excel worksheet is possible by calling the `AddPicture(name, image)`
+method on the `Drawings` property of an `ExcelWorksheet` object.
+
+The `Add-ExcelImage` example here demonstrates how to add a picture at a given
+cell location, and optionally resize the row and column to fit the image.
+
+## Running the example
+
+To try this example, run the script `AddImage.ps1`. The `Add-ExcelImage`
+function will be dot-sourced, and an Excel document will be created in the same
+folder with a sample data set. The Octocat image will then be embedded into
+Sheet1.
+
+The creation of the Excel document and the `System.Drawing.Image` object
+representing Octocat are properly disposed within a `finally` block to ensure
+that the resources are released, even if an error occurs in the `try` block.
+
+## Note about column and row sizing
+
+Care has been taken in this example to get the image placement to be just inside
+the cell border, and if the `-ResizeCell` switch is present, the height and width
+of the row and column will be increased, if needed, so that the bottom right of
+the image also lands just inside the cell border.
+
+The Excel row and column sizes are measured in "point" units rather than pixels,
+and a fixed multiplication factor is used to convert the size of the image in
+pixels, to the corresponding height and width values in Excel.
+
+It's possible that different DPI or text scaling options could result in
+imperfect column and row sizing and if a better strategy is found for converting
+the image dimensions to column and row sizes, this example will be updated.

+## Enumerate the Excel File Contents
+```powershell
+#Load the Excel file into a PSCustomObject
+$ExcelFile = Import-Excel "C:\Test\file.xlsx" -WorksheetName "Sheet1" 
+```
+
+## Visual of Data Structure
+The File C:\Test\file.xlsx contains  
+![ExcelFileContents](/images/FAQ_Images/ExcelFileContents.png)
+
+After loading this data into ```$ExcelFile``` the data is stored like:

+
+## Other Common Operations
+
+### Load a Column
+```powershell
+$SpecificColumn = $ExcelFile."anotherHeader" #loads column with the header "anotherHeader" -- data stored in an array
+```
+
+### Load a Row
+```powershell
+$SpecificRow = $ExcelFile[1] #Loads row at index 1. Index 1 is the first row instead of 0. 
+```
+
+### Map Contents to Hashtable to Interpret Data

+```powershell
+$HashTable = @{}

+# Write to an Existing Excel File
+### Enumerate the Excel File
+The cmdlets ```Open-ExcelPackage``` and ```Close-ExcelPackage``` allow for direct modification to Excel file contents.
+```powershell
+$ExcelPkg = Open-ExcelPackage -Path  "C:\Test\file.xlsx"
+```
+Contents of file.xlsx:  
+![ExcelFileContents](/images/FAQ_Images/ExcelFileContents.png)
+### Enumerate the Worksheet to View or Modify the Data
+```powershell
+$WorkSheet = $ExcelPkg.Workbook.Worksheets["sheet1"].Cells #open excel worksheet cells from worksheet "sheet1"
+```
+Visual of data structure:  
+![DataStructureExcelPkg](/images/FAQ_Images/DataStructureExcelPkg.png)  
+A1 contains "someHeader", A2 contains "data1" etc.
+### Modify a Specific Value in a File 
+Values can be accessed by row, column. Similar to a 2D array.
+```powershell
+$WorkSheet[1,4].Value = "New Column Header" #Starts at index 1 not 0
+```
+Contents of file.xlsx after modifying:  
+![ExcelFileContentsPostAdd](/images/FAQ_Images/ExcelFileContentsPostAdd.png)  
+### Load Value at Specific Index
+```powershell
+$ValueAtIndex = $WorkSheet[2,1].Value #Loads the value at row 2, column A
+```
+```$ValueAtIndex``` now contains: ![ValueAtIndexData](/images/FAQ_Images/ValueAtIndexData.png)  
+### Save File After Modifying
+The changes will not display in the Excel file until Close-ExcelPackage is called.  
+```powershell
+Close-ExcelPackage $ExcelPkg #close and save changes made to the Excel file.
+```
+**Note**: If the file is currently in use, Close-ExcelPackage will return an error and will not save the information.

+        .SYNOPSIS
+        Helper method for executing Read-OleDbData with some basic defaults.
+
+        For additional help, see documentation for Read-OleDbData cmdlet.
+
+        .DESCRIPTION
+        Uses Read-OleDbData to execute a sql statement against a xlsx file. For finer grained control over the interaction, you may use that cmdlet. This cmdlet assumes a file path will be passed in and the connection string will be built with no headers and treating all results as text.
+
+        Running this command is equivalent to running the following:
+
+        $FullName = (Get-ChildItem $Path).FullName
+        Read-OleDbData `
+            -ConnectionString "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=$FullName;Extended Properties='Excel 12.0 Xml;HDR=NO;IMEX=1;'" `
+            -SqlStatement $Query
+
+        Note that this command uses the MICROSOFT.ACE.OLEDB provider and will not work without it.
+        
+        If needed, please download the appropriate package from https://www.microsoft.com/en-us/download/details.aspx?id=54920.

+# v7.5.2
+- Changed the switch `-NotAsDictionary` to `-Raw`. Works with `-Worksheetname *` reads all the sheets in the xlsx file and returns an array.
+
+# v7.5.1
+- Fixed `Import-Excel` - Reset `EndRow` and `EndColumn` in the correct place.
+# v7.5.0
+## Fixes
+
+- Importing multiple files with Import-Excel by pipeline uses only the first file for the row count https://github.com/dfinke/ImportExcel/issues/1172
+
+## New Features
+
+- Import-Excel now supports importing multiple sheets. It can either return a dictionary of all sheets, or as a single array of all sheets combined.
+    - `Import-Excel $xlfile *`                  # reads all sheets, returns all data in a dictionary
+    - `Import-Excel $xlfile * -NotAsDictionary` # reads all sheets, returns all data in a single array
+- Added helper functions. Useful for working with an Excel package via `Open-ExcelPackage` or `-PassThru` 
+    - `Enable-ExcelAutoFilter`
+    - `Enable-ExcelAutofit`
+    - `Get-ExcelSheetDimensionAddress`
+
+# v7.4.2
+
+- Thank you [James Mueller](https://github.com/jamesmmueller) Updated `ConvertFrom-ExcelToSQLInsert` to handle single quotes in the SQL statement.
+
+- Thank you to Josh Hendricks
+    - Add images to spreadsheets. [Check it out](https://github.com/dfinke/ImportExcel/tree/master/Examples/AddImage)
+        - Catch up with him on [GitHub](https://github.com/joshooaj) and [Twitter](https://twitter.com/joshooaj) for the idea
+
+# v7.4.1
+
+- Implements: https://github.com/dfinke/ImportExcel/issues/1111
+- Refactored ReZip into separate function
+- Deletes temp folder after rezipping
+- Added -ReZip to `Close-ExcelPackage`
+
+# v7.4.0
+
+- Thank you to [Max Goczall](https://github.com/muschebubusche) for this contribution!
+    - `ImportColumns` parameter added to `ImportExcel`. It is used to define which columns of the ExcelPackage should be imported.
+
+```powershell
+Import-Excel -Path $xlFile -ImportColumns @(6,7,12,25,46)
+```
+
+# v7.3.1
+
+- Added query Excel spreadsheets, with SQL queries!
+
+```powershell
+$query = 'select F2 as [Category], F5 as [Discount], F5*2 as [DiscountPlus] from [sheet1$A2:E11]'
+
+Invoke-ExcelQuery .\testOleDb.xlsx $query
+```
+
+![](./images/SQL-Spreadsheet.png)
