HI GCB,

 

Do you get the same issue on our download package demo(Do not integration with your site, just test the demo only)? 

 

Please test our online demo http://www.cutesoft.net/ASP.NET+Image+Gallery/ ? Can you see the image? Do you have the same issue as your site?

 

check the permission, make sure your site have the write/read permission of this folder.

 

Keep me posted.

 

Regards,
