Respectfully disagree, this is one more question on top of dozens of other questions! And the users that I now support, which are largely stamp collectors, typically have no idea what a plugin is. You are like me, you're too close to the technology!
For example, this page is for our upcoming club Zoom auction this weekend. https://stampsmarter.org/AuctionFil...SC_List.aspx
The page shown in the link is derived form an online input form which allows club members to upload their own high resolution (no size limit) images and automatically builds a linked thumbnail based upon the width of the image. Works great as long as the user has cropped their images but the issue is that the majority of users do not crop their images. So I am left with doing one of two things, either I spend a lot of time cropping their images for them or I invest a LOT of time training and teaching people how to use one of one thousand different graphics apps that they might have installed on whatever device they are using. Now multiple this time suck many times; I have given this online auction code to many different clubs and organizations and am also hosting it all for them.
