Page themes fixed...
The AFV ASSOCIATION was formed in 1964 to support the thoughts and research of all those interested in Armored Fighting Vehicles and related topics, such as AFV drawings. The emphasis has always been on sharing information and communicating with other members of similar interests; e.g. German armor, Japanese AFVs, or whatever.

Post subject: Page themes fixed...

The building superintendent worked all weekend and all the "AFV themes" (that's the page appearance that you get when you log in) are now fixed with full button functionality so if stark white is not your preference for viewing the forums, you can select any of three AFV motifs for your viewing pleasure (among others) and get full button options (like PM's, member profile viewing and such) as on the default C-C "theme".

I find just "AFV" is the easiest on my eyes in all light conditions, but your mileage may vary.

To set, login, click on "My Account", look under "Configuration" and click "My Preferences". Select a "theme" at top of the menu and be sure to save before you leave. Thereafter, when logging in, your preferred page view will be the one displayed.

Thanks to the maintenance crew for a job well done at no overtime charge!

Hmmm....it works for me. Doing it as I've always done it. It even resizes correctly:





Try doing it with a real image and then let me "edit" your post to see what your syntax was for linking it. As you have moderator tools, you can also look at the syntax in mine, which is working. Maybe you missed a bracket or something?

Great, thanks! I'm back to the AFV theme.

Is this the same issue I've reported here a couple of times recently? You used to be able to post a link with spaces in it, but no more. Unfortunately many of the pictures on PTC sit in folders like:

Album/US/M4 Sherman/BovingtonSherman.jpg

so they no longer display here. It also means that all the pictures I've posted here in the past no longer display, even though they haven't moved.

I'm not even sure how that would work...I've never used a computer that would let you save a filename with blank spaces in it (underscores, yes...that's why my name displays as it does on the forum..it would not accept blank spaces). I've asked admins, but this is a whole new format for files that's never worked for me.

It's not in the filename, it's in the link because one or more of the folders has a space in it (like /M4 Sherman/). For example, the pictures linked to on the bottom of this page worked fine when they were posted in November:

www.com-central.net/in...p;start=15

You can check they're valid by copying the bit between [img] and [/img] and pasting it into a browser.

You can check they're valid by copying the bit between [img] and [/img] and pasting it into a browser.


Yes, they are valid. We are looking into it further, but the best explanation is that the site owner has altered their settings to disallow hot-linking as a bandwidth control issue. Are you the site owner? Any changes to site management? Even if webpage owner, server management might have made changes.

Admin experimentation seems to support that's it's a disabled hot-linking capability from other servers/site owners, which is understandable.

It's generally encouraged that if one wants to posts images from elsewhere here at C-C, the direct link be provided so members can visit the website directly, or images be hosted on one's photo-hosting service (being mindful of image ownership issues, etc...something I'm sensitive to myself).

FYI, images loaded into one's C-C gallery here can be posted here, but not hot-linked to other sites.

Musta' been. I think that's one of your images I've uploaded to my photobucket account and posted here above. The photo posting function is working fine...the only problem is hot-linking from sites that have disallowed it (as your Com-Central gallery does).

I don't understand. I'm linking from my website and I haven't changed any settings. The only change is that pictures don't appear here now if they have a space in the folder name. They still appear fine on other sites, like HMVF.

If it's not a hotlinking block, then admins tells me that it's most likely the open spaces in the file/folder names. Servers that have recent updates are increasingly intolerant to that configuration. Spaces in file names is undoubtedly more convenient to read, but I always incorporate underscores to insure that they get stored/read/displayed correctly.

If you try renaming one as a test case with no spaces and then post successfully, then you'll have confirmation. I don't foresee the server being reconfigured to accommodate the file naming practice that incorporates blank spaces.
