When attempting to upload some images using copy-paste into the WYSIWYG (as I've done below) sometimes the GZ language filter will pickup words out of the Base64 encoded image string as "bad words" (which is likely to happen when you're parsing 2KB+ strings of pseudo-random text).

Solution would be to not check words between <img src=" and " but probably the same issue with posting certain random URL's.

(Or we could all promise to be adults and drop the filter all together)...

I've seen a couple of threads about this sort of thing in the past.

I particularly like how you've now managed to post those two bad words using an image.

andrewNZ: I've seen a couple of threads about this sort of thing in the past.

Well it was also rather coincidental that the words appeared in the two screenshots (one in each) I was trying to post showing VF login errors... which may have resembled what I was thinking when I hit the first error, then the second one.

Offending images here with offending string replaced with FUCX & Cunx respectively (so obviously not going to display properly):

That screenshot looks a lot larger than it needs to be and would probably have annoyed the mods on that basis anyway. But more helpfully.. maybe a lot less compression in the image (and going to b&w) and your base64 edit would not matter so much : ). Ok, I know it's not that helpful.

Or at least turn language filter off for subscribers, I would probably subscribe for that...

Language filters are essential.

Also get 500 errors quite often when trying to submit posts with pasted images and more often when sending PM with pasted images, probably related..

Not all browser support paste images and these may have problems sometimes. Suggest uploading to Geekzone and using the BBCODE.

Check your logs, I'd say likely some SQL error when trying to save the mass of text, or hitting some sort of char/byte limit.

I don't blame you though; I wouldn't want a bunch of essentially BLOBs being stuffed into my carefully optimised database however it's just oh so convenient for the end user..

Any plans on the horizon for a better image upload function then? (have seen requested a few times & would prob subscribe for that to).

As opposed to the;

Take screenshot
Save image
Go to upload > oh bugger over 500kb (What is it 1995..)
Find a program to resize
Re-upload
Copy-paste code...

An integrated uploader would be nice; or yeah could just get the base64 copy-paste working and make it the standard (sorting out the storage/optimisation backend - I'm sure the scripts already exist or probably an option in some WYSIWYG's to save base64 blobs to file on upload).

EDIT: Personally haven't come across any modern browsers that don't support images this way, loads of large sites do it however as mentioned you can sort that backend if you like and just convert to a file for display.

Iirc (it's been a while) I usually use a free external image host for this service and inline it with the bbcode img tag. Less steps in the process because many of those services provide simple small/medium/big choices and that's that. Yeah the host might disappear after a couple of years but it's not an issue for ephemeral discussions.

You know of a good one to use?

I don't really think about it. There are tons of them. I just use the first one that comes up in google search. Today that is http://postimage.org/ no login required and many resizing options. You could also look at http://tinypic.com/ - of the names I looked at today that one has the biggest financial backer - owned by Photobucket.

i tend to use imgur due to the fact that it takes easily 4 times as long to do the whole geekzone image upload system.

screenshot tool, instantly uploaded and in my clipboard, paste on geekzone.

Simple and effective.

used to use photobucket, but their servers can be so slow, and they do dodgy things to photos unless you include ~original which breaks in many browsers last i checked...

I went to imgur, got distracted looking the funny pictures then after about 10min forgot what I was doing there..
