Can someone help me with this problem? My jpg and gif pics on my site look clear and peferct when using a regular internet connection using a computer and labtop. My friend has a wireless usb plug internet with a labtop. My friend went on my site using his labtop usb connection and the pics on my site where very blurry and not clear. I have search all over online and have not found a single solution to this problem. However, I did try changing the pics to a png format and all the pics were clear using my computer and his wireless usb connection labtop. But there is one big problem, with png the images download extremely slow. Can anyone be so kind in providing any solutions to fix this problem? One more thing resizing and pixels adjustment do not work either. I willing to bet no one can give me the answer to this problem, but I will be very surprised if someone has the answer. Thanks for any help anyone can give.
I am not savvy and SUPER smart but I'll try. There is nothing wrong with your site and you should not have changed your images from jpeg to png. What your friend is experiencing is called "IMAGE COMPRESSION" and is often time used by networks that want to save on bandwidth. These networks advertise and boasts their fast connection speeds but give their subscribers crappy images. You can tell your friend to do this: On Chrome, install an extension called ModHeader. Activate it and then create a profile like the screenshot below. When ModHeader is active, Chrome will retrieve all the images' original quality instead of the compressed versions. The "Modify Headers" plugin for Firefox also does the job. I don't use Safari and Opera browsers so I don't know if there are plugins for them to fix compressed images. You can tell your visitors how they can view the images in high quality by making a post and showing them a tutorial.
I dont think i meet the requirements in your title but my theory is his browser is timing out loading the jpegs. Difficut to type an explanation as im on my phone but in the dialup days you would often see picture quality improving as a jpg loaded. This is due to the way jpg encoding works i believe. If thats the case altering encoding settings when creating the jpg for smaller size would help (at the cost of quality)
Thank you for responding my friend. You are indeed super savvy and smart because you hit the nail on the head. Finally, someone has figured this out for me. Thank you very very much for explaining this issue. As you know, many people are losing potential customers to this issue, due to the popularity of many people surfing the web from wireless and mobile devices. If you have any questions or need any type of assistance with any problems you may have, i will be more than glad to assist you with my knowledge. Don't hesitate to ask me anything.
You've received the best advice in the first 2 replies... My 2 cents would be not to bother because most people will have a fast connection and they will see the images right
It becomes a problem when you meet with clients at locations where you depend on hotspots and try to demonstrate a fantastic new website only to see grainy and crappy images. It is also a big problem when viewing products on eBay, you want to see items closely andas much detail as possible, this is where the compression mechanism fails, because it is not optional. But easy to bypass if you know how. The methods depend on device/browser so can't advise on every situation
Now I am not a super savvy person, but let me still try to answer your question There can be more than one reason why this is happening. 1. Your friend's internet connection might be slow. If so, try optimizing the image sizes and try uploading Progressive JPG images instead of PNG/Other high quality image formats. 2. You might be using a CDN to render the images which is having problem with your friend's connection provider. In that case, change the CDN provider. 3. The images are blurry themselves (which I don't think is the case). 4. Your friend has the browser zoomed in. Press CTRL + 0 to reset. 5. Your friend has a crappy monitor. Gift him a new one if so. Also try clearing the cache. It helps more often than not.
I think the poster is stating it is a USB mobile dongle that is providing the connection, therefore bands like 3G will show low quality compression images, the images will improve slightly H+ and 4G. png has no compression therefore the images will take longer to load. It has it advantages in addition to disadvantages. Think of being on a train and you try to visit a website full of jpgs, loads of them. If there was no compression then hit very low network signal which is common on trains then you have the page will continue/wait to try and load, and probably eventually will. Without the compression, you'd probably smash your phone off the window after losing your paitence loading a single page for a small extract of information
