TYPO3 Core

as for disabling style attributes for images - simply set this pageTS:
----
RTE.default.proc.entryHTMLparser_db.tags.img.allowedAttribs = class,alt,title,border,align,src,width,height
----
you can define there which attributes you would like to allow - same for any other HTML-Tag.

edit: sorry - there was a dot missing in the TS snippet

Hello,

it would be really great if one could disable some fields of the image dialogue, especially the margin stuff, because it makes rarely ever sense to have the same margins for top and bottom or left and right.

Prosit, Uschi

Sorry, this was not documented. If you set:

RTE.default.buttons.image.options.removeItems = image

then the properties editing tab for the current image will not be presented.

The manual will be updated for TYPO3 4.2.

Feature added in SVN TYPO3core trunk revision 2925 (for inclusion in TYPO3 4.2 beta1.
