Put all the one-inch photo files in the same folder, then run Photoshop and select "File → Automatic → Contact Table 2" to pop up the dialog box (Figure 1).
Click "Browse" to find the folder where the inch photos are stored. If there are multiple folders under this folder, you should select "Include all subfolders". Setting the height and width of thumbnails is a key step. If the resolution of most photos in your hand is around 100× 120 pixels, we set the width to 500 pixels and the height to 700 pixels to ensure the clarity of photos. Not too high. If it is too high, interpolation operation will lead to blurred photos. It is best to keep the aspect ratio of 7/ 10, because the aspect ratio of a 5-inch photo is 3.5/5. If it is not set according to this ratio, some photos will be cut off when they are developed.
Then select "RGB mode" as the mode and tick before "Merge all layers". You can choose any of the following options for gallery thumbnail location, set the column to 2 and the row to 3, and put a check in front of "Use file name for title" (the file name will be marked under each inch of photos, so it won't be confused because there are too many photos). Please refer to figure 1 for parameter setting, and confirm after setting.
If there are many photos in the folder, multiple files will be automatically generated during batch typesetting. We're done. Let's see if there are any problems. There may be some photos out of proportion. It doesn't matter. Use "Rectangular Box Selection Tool" to select photos out of scale, press "Ctrl+T" to transform freely, and drag both sides to adjust to the best effect. The final effect is shown in Figure 2.

Size change of digital photos
There is no such thing as changing the number of bytes.
If the picture size is changed (for example, the picture of 3M is changed to 500K)
Method 1: Reduce the picture resolution (the picture of 1024*768 is changed to 800*600).
Method 2: Reduce the image quality (high quality jpg is changed to low quality jpg).
Method 3: Modify the image format (ttf is converted into jpgjpg and gif).
Either way, the image quality will be lost.
Use PS to process photos, and choose the best quality when saving.
Who knows how to compress hundreds of m files to hundreds of k? This is basically difficult,
If it is hundreds of meters of multimedia files, such as video, pictures and audio files, the compression rate is very low. But you can reduce the file size by reducing the file quality. For example, reducing the resolution of video files, reducing the number of colors in picture files and reducing the bit rate of audio files are all ways to reduce the size by sacrificing the quality of multimedia files.
However, there are exceptions. 100M (black and white) bitmap files have a very high compression rate, and can be compressed to within1m. ..
In addition to the commonly used compression software, there are also some specialized professional compression software that optimize the algorithm for a file in order to achieve a higher compression rate.
Generally speaking, the requirements of LZ are difficult to meet.
