# Frequently Asked Questions

Here are some common answers to common questions. If you need more help you can always visit the TinyMCE Forum on the TinyMCE web site.

## Why does TinyMCE strip aways attributes or tags from my source?

You need to check out the "valid_elements" and "extended_valid_elements" option in the configuration. By default, TinyMCE only allows certain tags and attributes. TinyMCE also tries to follow the XHTML specification as much as possible (and so should you), this can cause some unexpected source changes, there are however configuration options to battle this issue, study the configuration options in details.

## TinyMCE changes the path of my images, why?

Different browsers handles images differently, TinyMCE tries to compensate for this and has its own convert URL functions. You can control the behavior through the configuration, check out the URL section in the configuration options.

## TinyMCE takes ages to load, is there a way to make it load quicker?

If you use PHP on your server you can use tiny_mce_gzip.php instead of tiny_mce.js in page script call. This PHP file bundles all .js files together into two HTTP requests instead of one for each plugin, language file and theme and it also GZip compresses these files.

## Can I use TinyMCE in my commercial application?

## TinyMCE stops working when placed in tabs or hidden divs?

Since Gecko based browsers Mozilla/Firefox has a bug where it looses designMode on iframes that are hidden a special option is needed that re-enables the design mode when reappearing after being hidden. Enable this option to resolve the issue: "auto_reset_designmode".
