TYPO3 Core

This effekt is caused by custom rte config files in different extensions, some also used in intro distribution
for example:
/bootstrap_package/Configuration/PageTS/RTE.txt:187
toolbarOrder ( ... imageeditor ...)

changed to:
toolbarOrder ( ... image ...)

Image button is there

Does this problem still exist in v8

I close this issue for now for the following reasons:

1. In TYPO3 v.8 there is no native support for images in CKEditor; you can use the extension https://extensions.typo3.org/extension/rte_ckeditor_image/
2. I failed to reproduce it with pure TYPO3, without extensions that alter the RTE interface, on both 6.2 and 7.6: the button is visible with all the RTE presets (demo, typical, minimal) selectable on the RTE configuration in Extension Manager
3. the file typo3/sysext/rtehtmlarea/Classes/RteHtmlAreaBase.php does not even exist anymore on TYPO3 7.6
4. I even tried to search for "imageeditor" in the RteHtmlarea folder, without finding that string (TYPO3 7.6)
5. I found no evidence of it even looking at:

https://github.com/benjaminkott/bootstrap_package/blob/BP_6-2/Configuration/PageTS/RTE.txt
https://github.com/benjaminkott/bootstrap_package/blob/BP_7-1/Configuration/PageTS/RTE.txt

If you think that this is the wrong decision, or have more information about how to reproduce it, please reopen it or open a new issue with a reference to this one.

Please keep in mind that TYPO3 6.2 is no more supported and TYPO3 7.6 is in "priority bugfix only" mode. Last but not the least, further requests about the maintenance of RTEHtmlArea should be addressed at https://github.com/FriendsOfTYPO3/rtehtmlarea

Thank you.
