Well . . . I'll make a few assumptions and see if it makes sense. Lets assume your mysql table looks like this:

create table IMAGES(
 ID int(4) primary key auto_increment,
 data MEDIUMBLOB,
 type int(4),
 name char(10),
 width int(3),
 height int(3)
);

create table IMAGETYPES(
 ID int(4) primary key auto_increment,
 name char(10),
 description char(10)
);

Then your sql to insert an image would be:

insert into IMAGES(data,name,width,height) values(?,?,?,?)
[download]

Ok, that SQL is then primed to go into a DBI call using execute (after prepare) or by a do. As its an insert I recommend a 'do' call.

The second table allows you (by using a JOIN) to retrieve the image type and hence print the correct header when printing the image (assuming thats what you want).

As for SendMail - get Linux.
LiveStreaming - you could try something with Real using a RAM file under Apache. But its probably a little advanced. I would get the image stuff working first.
