Just got this from a support ticket:
Currently TemplateToaster supports images (*.jpeg, *.jpg, *.bmp, *.png) only .To add '*.gif' image you can use some third party plugin at CMS end.
So, my issue is that I have to use a kludge workaround to build my site with a placeholder image and separately change it out at my hosting server side, including the editing of an html tag on the page desired because this software is designed to exclude use of a common internet standard image format. If by "CMS end" they mean my hosting server end, then how many people who need to use a WYSIWYG website tool have access to add plugins there?
So how do I access this "CMS end" of the software, and where might I find such a third party plugin to correct this defect in the Template Toaster software?
