Can I save a pic to my psp from the internet browser on the psp?

I wonder which web browser and operating system you are using.

Try reconfiguring the network settings.

maybe the singal is low!

If you have no wireless internet inside your house, then you can not get online.
However if you do, then go to the internet browser on the psp and try to search for google or some website. As it tries to connect hit the circle button to cancel the connection then it asks what connection to use. Select new connection and scan for your wireless internet. There may be a password, there may not. But go through everything. If you get through everything, you can have fun on the internet with the 4in. screen now. =D

Turn on your WLAN switch....
Go to Internet Browser....
Network Connection> [New Connection]> Scan> now *select an access point*,> *now check the info*...; SSID>WLAN Security Setting>net password (if required)> Address Settings; Custom> IP Address Setting; Automatic>DNS Setting;Automatic> Proxy Server;Do Not Use(your choice)> Internet Browser; Start>Enter the connection name; (your choice)>Setting List; *scroll through to see if the info are correct*> Press the O/X button to save settings.
Select connection....... DONE!

STEP 1: CONNECT YOUR PSP TO PC
The PSP can function as a USB Memory Stick Duo reader. Using this functionality, you can copy pictures, audio, and other content to and from your Memory Stick Duo. To access the Memory Stick Duo in your PSP from your PC, you'll need a USB cable that has a "Mini-B" connector (common for digital cameras) and a "Standard-A" connector (common for printers, etc). Plug the Mini-B side into the top of your PSP and the Standard-A side into your PC. From the PSP software, navigate to the top of the settings list and select "USB Connection." Your PC (Windows/Mac/Linux) should detect a new "Removable Disk Drive" that you can then access.
STEP 2: FORMAT YOUR MEMORY STICK
In order to be able to use your new memory stick on your PSP, you'll have to format it. When you format your memory stick, the formatting will create a set of new folders on your PSP: GAME, MUSIC, PHOTO, and SAVEDATA.
STEP 3: EXTRACT THE SAVED GAME
This process will greatly depend on which software you use to extract zip files. WinRAR for instance offers the "extract here" option, which will simply extract the contents of a zip file to it's current directory.
STEP 4: TRANSFER SAVE GAME TO "SAVEDATA" FOLDER
Just copy the folder you have just extracted, and paste it into the PSP's "SAVEDATA" folder. But, BEWARE!, to any folder overwrite warnings! Because the PSP save game folders use the same names for the same games, copying folders into these locations could lead to lost data. For this reason, we recommend that you backup your old save games before overwriting them. For Example, I would simply rename a folder like "ULPS0004" to "ULPS0004_backup."
STEP 5: EXIT USB MODE
Because your PSP has been in USB Mode throughout this process, just push X to exit. Then you can safely disconnect your PSP from your PC.
STEP 6: VERIFY TRANSFER OF SAVE DATA
To verify the integrity of the SAVE GAME data you have just transferred, use the PSP's built-in Save Data Utility. Select it from the "Game" menu.
That's it, simple and smooth.

I don't think you can directly play movies from your web browser. Maybe if you have the latest firmware it will work.( i think the latest is around 3.80) If you want to add movies from the internet and SAVE them onto your PSP, then follow these steps:
1. Download Firefox if you don't have it
2. Goto the page with the movie you want
3. Goto File in the top left corner
4. Select Save Page as
5. Save it anywhere you want
6. Connect your PSP to your USB, and enter USB mode with it
