Refining the site on symfony 2

Hello

There is an ad site.
The ad-adding feature has broken down.
When you create an ad, you dont load pictures. We have to fix it. Pictures are stored in the cloud server, but there is no creation of sub-catalogues in the picture folder, because of this the folder limit is exceeded and nothing else can be added to it.
It is necessary to make that when unloading pictures, created on the first symbols of the picture file and there were stored pictures.

It also stopped sending email messages to the administrator address.

First of all, these two problems need to be solved.

Then there is a list of improvements to the site, which we will take up when this task is successfully completed.
