I hard reset my phone and now it asking me for the email that was synced to the phone and i dont know it so now what am i supposed to do???

you have to delete your phone memory to reset your email again

if you dont know your email address then there is nothing to reset.
ask someone that sent you an email to look up your address

if you dont know what it is it's obviously not that important your better off just setting up a new gmail account

write down and or save your address and passwords

You can forward that email to a different email using a computer and than using a computer to delete that email from the old email account and than sync the account to your phone that way the email will never be sync so the picture will never end up on your phone.

It sounds like you may have a software error from your device. Chances are good a hard reset would resolve the issue. A hard reset is when you reset the device and restore it to factory settings. Note doing this will delete all data from your device, so it would be wise to back everything up first!
Also, since your Palm Pre has a feature called a Palm Profile, ENSURE with 100% certainty that you have the correct email address and password for your palm profile. This info will be very helpful and required to re-sync all your contact data to your device.
Once you have backed up and are ready to hard reset your device;

• Open Device Info
• Phone Reset Options
• Tap Partial Erase Partial Erase will not erase files on the "USB" storage of the device, which include your photos. It will remove applications you've installed and other files.

It will ask you to confirm your setting. It will then reboot your phone. Do not be alarmed if your phone sits at a pulsing PALM logo, this is normal and does take approximately 5 minutes.
Once it is powered back up, it will ask for your palm profile info (email and password) I mentioned early. This will begin the syncing of your contact data and some of your settings. This should fix the messaging issue! Let me know how this works for you and if I can be any more assistance.

Try Hard Resetting it. It brings your phone to Manufacturers setting. Though You'll be loosing all your data (Try syncing with your comp if you can) but you'll be able to use your handset. Just go through your user manual for the hard reset.
