No problem, like camera very much

The instructions below are to change the thumbnail picture.
Just change it for a blank picture or something that won't matter.


To add/change a profile picture or change your current profile picture:

1. Go to your profile and hover over your profile picture.
2. Click Update Profile Picture.
3. You can:
   • Upload a photo from your computer.
   • Add frame.
   • Select a photo you've already uploaded or one you're tagged in.
4. Crop your photo and click Save. If you don't want to crop your photo, click Skip Cropping in the bottom left, then click Save.

For best quality, your profile picture should be at least 320 pixels wide and 320 pixels tall.
Note: Your current profile picture is always public.

JigZone Photo Upload accepts pictures of JPG and GIF formats only. All puzzle pictures are a fixed dimension, 400 pixels wide by 300 pixels high:All puzzle pictures are stored with a maximum file size of 20KB (20,480 bytes). Photos which have a file size greater than 20KB will be automatically compressed, which could result in a loss of picture quality. For fast uploading and maximum picture quality, we recommend that your edit your pictures to be 400 pixels wide by 300 pixels high and have a file size no greater than 20KB before uploading them.Note: GIF type images cannot be automatically re-sized and must be formatted to 400 x 300 and less than 20KB before being uploaded.To limit the bandwidth costs of this free service, at this time the file size of a photo upload is limited to 2M or 2,097,152 bytes. Large sized photos could take several minutes to upload. During this time the upload page will remain on the screen.

Most smart phones/tables do not allow you to go that low on taking photos. But you can resize a photo after taking it, by downloading a free app like ImageShrink from the Play Store.

Cover photos are 851 pixels wide and 315 pixels tall. If you upload an image that's smaller than these dimensions, it will be stretched to this larger size. The image you upload must be at least 399 pixels wide and 150 pixels tall. But if you have an image of high resolution, you must first edit it using Photoshop or any image processor.

The size of the file depends mostly on the resolution. Higher resolution gives more detail and the picture can be printed larger without showing pixelation, but this requires more data, so the files are larger. Recent cameras offer resolutions stated in terms of 10 or 14 megapixels. That much data needs a large file to store it. Reducing the resolution in the camera settings to 5 or 3 megapixels (or less) will give you a much smaller file. In the camera, this will usually be specified in terms of pixels wide by pixels deep (e.g. 1600x1200).

You can reduce the size of a picture in a photo editing program (resize or resample), which will also reduce the resolution.

Compressing the file is not likely to help much. Usually these files are in a format (.jpg) that is already compressed. The camera may allow more than one quality of compression. You can set this to compress the pics more, but this will reduce the quality of the image and introduce more digital noise. It is also possible to increase the amount of compression when saving an edited file in a photo editor, by specifying this at the point of saving. None of these will make as large a difference as reducing the resolution by resizing.

A wide screen display requires setting the appearance
procedures
1. right click on a space on the desktop without icons
2. select from a list prompt the settings with click should provide link with which to select the appearance setting
3. choose from the display icon prompt after clicking a pixel quality
4. a larger figure chosen from the list should decompress the screen pixels creating clear pictures though adjusted screen to fit the area

A couple of things - I don't think you mean 500 megapixels (that is a lot!) but I assume you mean you expected a high resolution image. You may have it! The dpi setting is largely irrelevant (for photographers) as it simply relates number of pixels to a (notional) print size. Thus an image that is 3000 pixels wide (say) would print out to 10 inches at 300 dpi (3000/300) or 40 inches (approx) at 72 dpi (3000/72). the image has the same information /resolution - it's just "spread" further on the larger print. You can easily change the nominal dpi in e.g. Photshop Elements but it won't affect your image quality.
If however you are getting low resolution images when setting the camera differently that's something different. I would need extra info to help there but pssibly check if the camera was set to RAW and maybe you were looking at the (small) JPEG usually saved with it?

Go to user manual and check Image size settings as shown in below...

All pictures have 24-bit pixel depth, or 16 million colors at 144 dots per inch. The high resolution setting produces a standard size photo, 4.44" x 3.33" at 640 x 480 pixels. A wallet size photo of 2.22" x 1.67" at 320 x 240 pixels is produced using the standard resolution setting. Example: A picture with dimensions of 4.44" x 3.33" at a pixel count of 640 x 480 will have the same dpi as the same picture at a 320 x 240 pixel count with dimensions of 2.22" x 1.67" (dpi=144 x 144 or 20736 pixels per square inch). The larger picture will have a much higher resolution due to the fact that four times the pixels will define the same section of the picture in the larger photograph.
