If you have ugpraded TTG SimpleViewer from SimpleViewer-Standard to SimpleViewer-Pro, then there will be no limit to the number of images you can have in your gallery when using a local XML file to list the images.
There is, however, a limit of 500 images when using Flickr as the image source. This limit is imposed by Flickr (rather than SimpleViewer). It is the maximum number of images returned by a Flickr API search (such as that performed by SimpleViewer to fetch the images from Flickr).
Please see the per-page API Option on this Flickr help page: http://www.flickr.com/services/api/flic … earch.html
Number of photos to return per page. If this argument is omitted, it defaults to 100. The maximum allowed value is 500.
I have looked through the TTG SimpleViewer files and can find no such limit imposed by the plugin itself.
It you continue to experience difficulties, please post the URL of your gallery so that we can take a look.
Also, TTG SimpleViewer has its own forum here which may help further.
