Firefox does not execute:imageArea.innerHTML = "<image alt='&#x" +parts[1]+";' src='/images/dictionary/"+parts[1]+".jpg'/>";I .jpg is replaced by gif, if does fine. Setting httpd_read_user_content=1(SELinux suggested) makes the area totally black black.

From SELinux:
SELinux is preventing /usr/sbin/httpd from 'read' accesses on the file /var/www/html/images/dictionary/9F9F.jpg.
***** Plugin catchall_boolean (89.3 confidence) suggests *******************
If you want to allow httpd to read user content
Then you must tell SELinux about this by enabling the 'httpd_read_user_content' boolean.
Do
setsebool -P httpd_read_user_content 1
***** Plugin catchall (11.6 confidence) suggests ***************************
If you believe that httpd should be allowed read access on the 9F9F.jpg file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep /usr/sbin/httpd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
