This is an issue reported to Microsoft Connect.  
From [SSRS 2008 How to get the best image quality possible?](https://connect.microsoft.com/SQLServer/feedback/details/493441/):

> The image behavior you see in PDF is a result of some image conversions that the PDF renderer does, based on how the PDF specification requires that serialize images into PDF.
>
>We know it's not ideal, and we classify the loss of image quality as a product issue. Therefore, it's difficult to really say what to do to get the best quality image. 
>
>**Anecdotally, I have heard that customers have good results when the original image is a BMP**

I have a report that renders images (jpg) that have been collected from various sources.  This works fine within the report viewer, and when exporting via Excel.  

However, when exporting to PDF, about 5% of the images are rendered incorrectly as can be seen below, with the original on the left, and what is rendered on the right;

![enter image description here][2] ![rendered image image][1]

**I find that if I open up one of these images in mspaint, and just click save, on the next report-run the image is now rendered correctly.**

Are there any rules as to what image properties/format are valid for SSRS to render the image correctly within a PDF?  Essentially I'd like to somehow find these images that will render incorrectly before the report is run and fix them prior...

SSRS can't properly render *some* images within PDF

You are likely getting the error message `Report Builder was unable to paste successfully` because somewhere in the grid there is a cell that uses Custom Code From the Report

> i.e. you cannot copy a textbox with this custom code: “Code.MyCustomeCode()”  
 - [Report Builder was unable to paste successfully][1] 

This has been a reported bug since SSRS 2008:

> When using Visual Studio 2008 to create new reports, we cannot copy and paste multiple textboxes in a tablix, and receive a popup error stating "Report Builder was unable to paste successfully"  
 - [Unable to copy and paste textboxes in SSRS reports with Custom Code after 2008 R2 SP2 upgrade][2]

**Workaround**:

1. **Open up the XML** view for the report, either in Visual Studio by right clicking the report and selecting *View Code*, or by editing in any text editor.
2. **Comment out `Code.`** blocks.  <kbd>Ctrl</kbd> + <kbd>F</kbd> your way through the document looking for `Code.`.  The goal is to preserve the code in some way, while temporarily commenting out the line.  Depending on your actual code, this might be different, but I here's what I like to do:
   * *Find*: &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`=Code.`
   * *Replace With*: `='Code.`
3. Go back to the Designer View and **Copy and Paste the Tablix**.  You can do this by right clicking the top left corner of the tablix control:  
   ![Copy Tablix](http://i.imgur.com/iNJQuqq.png)
4. Go back to the XML View and **reverse the find and replace**
   * *Find*: &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`='Code.`
   * *Replace With*: `=Code.`

You should be all set!

> **Note**: You cannot just copy the `<tablix>` block in the XML view after step 1 because it will create elements with the same exact `name` property

I have a tablix that has data for one day, and I need to have the same data at the bottom but in 3 different lines.  I'd like to copy the main day table 3 times at the bottom, and then use different datasets for each one.

I tried copying the tablix and pasting it into the `Body` beneath the tablix, but I get the following error:

> Report Builder was unable to paste successfully.

How can I accomplish the copy and paste? Or if that isn't possible, is there another way to do what I am trying to accomplish?
