how to add file upload field to the certain section I want

How to add the new field and particularly the image upload orf file upload section to any module we want for example how do I add the image upload to the contact section of the suiteCRM.

What is the authentic and better ways of doing it .
Can it be done from the administration developers tools sections or we need a code level changes to be done for the addition and removal of it .

Thanks
SuiteCRM newbie

Yes it can be done via administration panel

Go to Studio and select a module … and go to fields and then add a field by selecting IMAGE in the field type.

After creating the field go to layouts and place the filed inside the layout

Cheers!

I have tried the same process but it is not working . This is what I tried

  1. For example to add the fields to the contract section
  2. [After visiting the studio in administration panel select the contract
  3. Add the new fields i wish to for example i added url by giving the name and label name
  4. Going back to the layout section , drag and dropped the latest field added to the section i want
  5. SAVED it

Checking to see if the new fields have appeared but not .Also the fields added has * asterik in front of it in the fields list . it appears like this * drivelink_c if I add drivelink it shows up with * in the list
The title fields in the fields list are also undefined as shown in the picture below

NOTE:

All the dialog box that appears are displaying undefined too. Is it because some setting are missing in core or what. Want to solve the both issues

asterisk mark on fields are normal, it used to show those fields are custom fields. Please deploy the changes using the studio and do a repair and rebuild

Undefined occurs mostly because of the bad file permission… Please check studio module files got enough permission
