Hello Edelina,

Please ensure each image is smaller than 500KB  -  then hold the 'CTRL' key whilst entering Preview mode in WebSite X5.  Wait for the Preview to build fully by watching the progress bar at the bottom right of the screen.

Then check your pages in Preview mode to ensure that all images are present.  If any are missing then go back to the Gallery or Image Object in question, and check the file path to the image is correct, and that the image actually physically exists at the same location when you browse to it in Windows Explorer.  Be especially careful where images may have been stored on removable drives, such as USB flash drives or portable hard drives.

Image Generation errors usually result from trying to work with images which are too large (remember that image file size should be as small as possible for the web), too numerous (too many images in one Gallery, for example  -  split into smaller Galleries), or old, redundant file paths where the image has been moved from its original location.

Please let us know how you get on.

Kind regards,

Paul

You need to resize your images. I had tons of the same problem, until I downsized the images to 1280 pixels
