Difficulty Viewing PDF Images In Browser

In order to view PDF images you must install Acrobat Reader which can be obtained from Adobe.

Two settings within Adobe Reader seem to have the greatest impact on the quality of drawing images: "Smooth line art" and "Smooth images". These two settings can be found within the "Page Display" category, under the "Edit", "Preferences" menu item. The "Smooth line art" checkbox should be un-checked. The "Smooth images" checkbox should be checked.

Difficulty Viewing TIF Images In Browser

If you are experiencing difficulty viewing TIF images, you most likely have one of two problems. Either you do not have a viewer associated with TIF files or you have installed a browser plug-in, such as QuickTime®, which associates itself with TIF files even though it has difficulty displaying them.

For the most part, if you are a Windows user, a good TIF viewer comes free of charge as part of the operating system install and is normally set as the default TIF viewer. Because of this, Windows users will usually have a good viewer associated with TIF files at the file association level. You can check which viewer is installed as the default for TIFs by launching Windows Explorer and selecting the Tools>Folder Options menu selection and then selecting the "File Types" tab. (Note that navigation to the file associations area may vary depending on which flavor of Windows you are running but generally it is an option/preference setting off of the directory/file navigation.) Once there, scroll down to the TIF/TIFF file type and examine which application is associated with the type. You can verify that the associated viewer works with TIF/TIFF files by double clicking on any TIF/TIFF file already on your file system. If the viewer works for TIFs in this fashion but not via your browser, then you probably have the more common problem where a browser plug-in is intercepting the TIF request prior to the normal file type association. If the viewer does not work when you load a TIF directly off your file system, then you must acquire and install a suitable TIF viewer and associate it with the TIF/TIFF file type in the file associations area.

If you are having problems with a browser plug-in then the offending plug-in's association with TIF images must be disabled to correct the problem. In the case of QuickTime®, there are a couple of ways to accomplish this. If you can find the QuickTime® configuration program in your Control Panel, the easiest approach is as follows: double click on the QuickTime® icon in the Control Panel, select "Browser Plugin" in the drop down box, click the "Mime settings" button, scroll down to "Images", click on the "+" symbol, scroll down to the .tif/.tiff entries and de-select. A second method is to launch the QuickTime® player, click on the Edit>Preferences>QuickTime Preferences menu selection and then follow the instructions for the first method from that point on. Either of these approaches will, in effect, re-instate your default TIF viewer association and may solve the problem. If it does not, then you may have an additional plug-in intercepting the TIF request. That plug-in will need to be disabled in a similar fashion.
