Dear kengelhardt,
We are considering using DotNetGallery.
What images types can be in the file system and produce thumbnail images?
A: It supports common used image types such as jpg,jpeg,gif,png,bmp.
Also, can just the thumbnail feature be used? We don't need the upload function; we have an existing upload using CuteUpload.
A: Ajax Uploader is builted in DotNetGallery, The Ajax Uploader in Image Gallery allows you select and upload multiple image files and cancel running file uploads, add new files during uploading. I advice you do not disable the built in upload feature. If you prefer disable it, please open "CuteSoft_Client\Gallery\Editor\Explorer\Code.js", the following several lines display the upload button, you can comment them:
var uploadbtn=CreateEditorButton("Images/standard-upload.png",GalleryLocalize.CLICK_UPLOADFILES);
leftToolbar.appendChild(uploadbtn);
browser.SetMantleButton(uploadbtn);
Thank you for asking
