I'm aware the image uploading procedure on Sumea for our members is something that needs to be simplified - in fact, it's quite possible to make it extremely simple and failsafe, but it comes at a cost. It's going to require me to purchase an asp component - something like [url="http://www.aspupload.com/aspjpeg.html"]this would be ideal[/url] (costing $150 US or $205 AUS). I may have to see if anyone is willing to sponsor us for it (unfortunately I don't have Visa, MasterCard and American Express to pay for it either [:P]), but basically with this component installed, it'll make image uploading so much easier. All you would have to do is upload your large images then write your news. The component will make the thumbnails for you, and you won't have to worry about the naming conventions, file sizes, and image dimensions.
Also, I'm pretty sure there are already components installed which can check images for their width and height details, so basically we wouldn't need members sticking to 800x600 images either (although I do like that size for consistency).
Anyway, that's the plan. [:)] I'm also planning to make the Sumea Calendar a bit more flashy. You know, like a proper calendar graphic showing the current month and days with events marked etc..
