I have a custom .aspx page containing a table with 16 Interactive Buttons on it. All buttons were created in SharePoint Designer (Insert -> Interactive Button) successfully. I'm now trying to add another button using the same method, but the button images are not uploading to the images folder when i attempt to save. I'm not being prompted where to upload the images. When i refer back to the code, it's looking for the "buttonC.jpg" on my LOCAL drive: C:/Users/myprofile/AppData/Local/Microsoft/Windows/Temporary%20Internet%20Files/WebTempDir/
how can i get these custom button images to upload when i save the .aspx page?
