Setting cannon Even on the L setting my camera's jpeg files are on average only 2.5 mb. Surely the files should be bigger? The manuals tells me they could be up to 18mb. Why so small?

Both are just the programs to put the pictures on the computer and edit the pictures. The pictures should be on the computer.
Try to find the folders, where the programmes did store the jpegs. Or if you shoot RAW, also the RAW files.
Copy all the pictures in these folders to a different drive. The best is an external USB drive. Only after you are sure you did copy (do NOT MOVE the pictures but COPY because move will delete the originals) all the pictures to a safe place, start finding out, what could be wrong with the Olympus software.

For lots of camera's you can chose same file size, but you are right I would not trust that.
Even when you have a very good computer, with a very good hard drive, please do make backups regularly. And actually one backup is no backup. Always try to have two backups on two different media.

Need more help? just let me know.

That is not exactly to calculate. It depends on the stored image sizeand quality.
Small pictures could be 400KB a piece, but large ones easily can go up to 6GB
a piece. If you know thye avaerage size of your pictures, you can calculate it.

The internal memory for this camera is 8 MB.

The manual indicates using memory cards of size 8 to 128 MB, so this is an early SD memory camera, following the original SD standard. Do not try SDHC or SDXC cards. The camera will support a 1 GB card. It *might* support a 2 or 4 GB card, but since this is a 2 Mpixel camera, a 512 MB or 1 GB card will allow you to save thousands of jpeg format pictures.

Yes, any Secure Digital (SD) memory card can be put into your hp Photosmart 620 camera safely. I would not go any bigger than 4 GB due to the limitations of some computers that you may use to download and process your photographs. And, you probably will want to pull off the phototgraphs and put them onto your computer for long term storage or for printing. That camera normally makes about a 1 Mb file for a JPEG image file. It will take a long time for you to fill up a 2 GB card; around 2,000 photographs.

Please open the "paint" from"start/all pograms/accessories/paint".

one when you open the paint, click on file and select the option scanner and camera wizard.

when it open click on scan and when scan get complete click on file and "save as " and select the formate "jpeg" and save it.

are all the files the same extension? JPEG and JPG are different as far as how they are encoded? even if you NAME THEM .JPG or .JPEG it is the encoding method you choose to export them as that makes the difference. As in Coreldraw for example. They is a JPEG and JPG export filter.

If you convert them to JPEG then you will be able to store alot more, The newer the camera the bigger the picture size.

To do this, simply open the picture in Paint, and Press save and save the file type as JPEG and over write the file

hope this helps

the general rule is a jpeg is halve the mb of the resolution-6 mp =3mb file size-kodak uses a ton of compression and this is the main reason why-put a memory card in a kodak and you pick up about 20-30% more capacity than other brands!

The files are compressed. A typical 5mp file should be around 2.5 Mb in size. A 7mp camera produces a file of abot 3.5 Mb.

think what is happening is that Pentax is not using the maximum JPEG quality value for their high quality setting. I re-saved an image in Photoshop last night, and the JPEG quality value was set to 9. I increased it to 12, and ended up with a 3.5 MB file.
