I am using Performs component on our site.It is for Joomla 1.0.
We needed a way to get the news from the public, with the option to attach a picture, movie, etc.
While many form components does the basic functions, textfields, mail, radio buttons, there aren’t many to allow file upload.
See it in action : LINK
Sorry about the foreign language but you can always GTranslate the page 🙂
Another nice feature of this component is that after the form is submited, the admin recieves a mail with details about what was written (configurable), file(s) uploaded, size, etc.
I don’t know if there is another similar component for J1.5 but here is the link for this : LINK
Kinda old but it does its job. 🙂
