Ok, I've done some initial searching, and I'm kind of stunned this hasn't come up more - or maybe I'm using the wrong search phrase(s) or missing an already-implemented feature... anyway...

Resizing images on upload.  Particularly through the 'core' FCKEdit control.  I keep running into a problem where users are constantly struggling with the concept of resizing before they upload. In reality, it can be a bit much for some less-technical users to comprehend 'measured in pixels',  '300 vs 72dpi', 'resolution' or the difference between image size and file size.  Yes, I know this is design 101 for many of us, but I have several clients who chose us (and by proxy, the DNN system) because of the ease of use and administration. However, I now am constantly finding myself going in and manually correcting many of these issues as they affect not only site performance (more than 2x 2mb+ images in the portal root can cause the Image Browser to hang while loading, even on high speed connections) but for the sake of overall site size on my servers.

I understand that as of 5.2 we now have Telerik controls, and I'm curious if this will extend into the core Text/HTML editor as I notice in the "Modules" section there is no longer a HTML / Text section. I would prefer to find this solution within the 'core' functions/features of DNN as the more modules each website takes, the more places things can go wrong during upgrades, maintenance, etc.

Thoughts? Corrections? Someone wanna beat me down with the 'clue' stick because I missed something obvious? =)

Thanks!

Wells-

Yes, this has been a problem for me too.  The core has a generic Max Upload size setting but that is for the entire portal - images, docs, everything.  Telerick's RADEditor has some settings too but they are also portal wide.

The best upload module/control for DNN is Fatgeorge's Upload control for Xmod.  Max file size, max height, max width, auto-watermarking, auto -thumbnail generation, disk quota's, resize on upload, and tons of other settings. All settings are per instance.

I am looking into Telerik's stand-alone upload control to see if it's settings can be configured per instance.  It looks to have some pretty decent validation options. It is also included in their DNN Trial modules install (along with RADEditor) so you can install it in CE. Configuring Telerik's controls can sometimes be fairly tough with some options needing to be set in the code-behind.

Yep, I've worked with FatGeorge's solution before when I was running Xmod on some of my sites. However, the majority of my headaches come from users who are editing inside the HTML module. I understand part of the complexity in coding for something like this, however I would not too opposed to a method that took the full size image and dumped it to a specified directory, and then create a resized image in a 'thumbnail' directory (preferably to a user-defined size).

Otherwise, I'm guessing this is more a FCKEditor-specific issue and as such maybe the fix is locating a 3rd party editor with this functionality (if one exists). However, I prefer to avoid too many changes to 'core' features and modules.
