Tricky or not ? upload & rename, store image-filenames in database

Tricky or not ? 

(I use php3, unix, apache, mysql)
Can anybody give advice how can this can be done?

I want to upload images together with other data of a record and store the data together with the related fileNAMES.in 1 mysql-record.

1. First the data part of the record is entered (form1=data) and stored. 
2. After the dataform was submitted from this dataform a image-upload form (form2=imagedata) should be called
.
3. The imagefiles shall be browsed on the local filesystem (using <input type=file ....> for each image-file 
4. BUT then the file shall be stored renamed to a filename consisting of the ID of the previously entered data-record plus a sequential image-number). 

Thanks for pointing a way or hints about resembling samples
