Verification Code Image Not Always Showing

[whatname]

Hello,

Problem - The image is missing, about half the time, for the verification code on image upload. I have version 1.7.4

I set myself up as a user and this happens about half the time. I know that there are images available and the captcha files seem to be ok. When the image is missing, I just click on it to get a new one. I usually do get a new image. Sometimes I have to click several times. I don't have the application linked to the rest of my site so no one but myself is using it yet.

I searched the forum and found nothing. Perhaps the problem is in the file that calls the captcha. I don't know what file that would be. I don't want to disable the captcha so any help is appreciated.

Love this application! It was very easy to customize and is very user friendly.
Thanks so much,
Jessica

My server PHP version is 4.4.4
My 4Images version is 1.7.4

I deleted the files and started with a new program.

I reset the template files but changed nothing else. My url is http://www.mywaynesboro.com/photos
All of the work on the upload and template change was made yesterday. I also registered two users other than myself. The verification code was there for both the admin image uploads as well as the registered user uploads.

This morning when I went in to add more images, the verification code is only there half the time.

My error log reads like this:

[21-Nov-2007 09:36:28] PHP Warning:  imagettftext() [<a href='function.imagettftext'>function.imagettftext</a>]: Could not read font in /home/mywayne/public_html/photos/includes/captcha_utils.php on line 168

I know nothing of php except that I could easily mess it up if I try to fix it. I did try a fix for the config.php file that sets each occurrence but it only made the entire photo area a blank page. This is the link to the fix that didn't work for me: http://www.4homepages.de/forum/index.php?topic=14690.0

Please help, the site is live and there will be visitors trying to register and load images.

Thank you for your time,

Let me also say that I am not using a special template. I just changed the .html pages to customize the look. All of the original function is still there, only the look has changed.

This is a very good resource as well!

"No need. Go to global.php file and find: $captcha_enable_comments = 1 - change to 0. "

I am finding alot of ways to get around the problem but no fix. I want to use the verification code. It worked great the first day. I don't mind using it as the admin. I like that only real people will be able to post to my photo gallery.

Let me know if I need to give any other information. I have included my error messages above.

Thanks so much for all of the great work you have done in making this program so wonderful. This is the best image gallery that I have found and so easy to use, for both admin and users. Your time is very valuable and so I say Thank You again for taking your time and helping others by providing this forum.

Have a great day!
Jessica

I have the same problem: sometimes it works, but more often I see a little red cross instead of the picture.

(FAQ -> http://www.4homepages.de/forum/index.php?topic=14690.0 did not help)

Just refreshed your captcha for over 50 times and didn't see a single broken image...maybe its something with your browser?

@olgaart

... here is a Tutorial ... [TUT] Change of the CAPTCHA-Design ...

[olgaart]

Hi V@no , fixed it yesterday, found in the captcha images directory, that my ftp-programme addad a log-file, and when it was chosen as a captcha background, it did not work.
mawenzi, thanks for the link, you are right the backgrounds do not fit the grey template, will try to change it.

Many thanks!

Hi, all;
it must be in the FAQ! .

Many FTP tools uses to write their own log in uploaded directories, as WSFTP or CPanel's utility, writing a "wsftp.log" or similar file. CAPTCHA routine doesn't mind what is this file's extension and tries to use it as background, when placed in captcha/backgrounds/ directory.

Maybe users that tried to customize CAPTCHA design would face such problem, because of the file "thumbs.db" that MS Windows generates.

Just an advice: before uploading your files to your website, perform a search in the directory where you files are. Search for files having extensions like ".log", ".db", ".bak"... and delete them all before uploading the directory by FTP. Once uploaded, check your website to find such files.

At last, look at your FTP tool configuration. It must exist a way to avoid generating such logs (i.e. FileZilla does not generate any unwanted file).

Thanks olgaart for having given us the clue!
