Creating a module for CRMVtiger?

Question

PHP

The module has a field for loading "pictures", the point is that it does not load a picture, it just ignores it, i.e. the field is there, the picture is selected but not loaded and, accordingly, does not display after the record is created.
I also tried to create a field through the "Designer" module.
I walked on American and German forums, there are questions but no answers, that is, there are answers, but they are in the style of "Xs", "There it is done through some kind of ass", etc., I laughed and cried for a long time at the same time.

Answer 1

did not consider another CRM? sugar for example
When I was faced with the task of choosing a crm, I also tinkered with the tiger for a very long time, and eventually spat on it
